Bought this as a closer-to-nature replacement for Neo Strata Smoothing Cream 10%AHA, which I had been using for some years. Had no irritation whatsoever, except when I tried layering a moisturizer over the DeVita gel, so best used as a stand-alone product. Love it!

I've been searching for a gel based glycolic acid for some time and I've found Devita to be it. It also has around 10% strength, but it felt so good on my face, I didn't experience any strong sensation. It felt cooling after applying, left my face radiant and smooth the next morning! I noticed that this gel kept me from having breakouts too! Definitely a well worth investment for skin, will buy it again.

I loved it! While I used the third bottle, but it is the result: the person as a whole was brighter spots (I had had from the sun) paled in general skin looks fresh, smooth nasolabial wrinkles. I think this is the merit of acids, and of Cordyceps fungi. Hopefully, by the end of the bottle still brighten dark spots, it bothered me the most!

i have combination oily skin and after using this for more than a week, skin is clearer and smoother. I do not have acne but i noticed that my blackheads is lesser than before. I did not feel any tingling sensation but overall it works. Great product!
